A force of 200 N is required to keep an object sliding at a constant speed of 2 m/s across a rough floor. How much power is being expended to maintain this motion?

Sagot :

Force x speed = power
200 x 2 = 400 watts

Answer:

Explanation:

Power = work/time

Work = force x distance

power = force X distance/time (velocity)

power = 200N x 2m/s

power = 400 joules
